## What is Exxentric?

The kMeter provides real-time feedback for training sessions using the Exxentric kBox, kPulley, LegExx and LegFlexx. The devices are used by athletes and rehab patients for a wide array of flywheel training applications. The Exxentric app connects to the kBox, kPulley, LegExx and LegFlexx and enables you to display and record training data including power, overload, range of motion and force.
 
The app provides coaching functionality where coaches can keep track and register training for clients.

The app also allows users to view workout content in the form of videos to be used as a guide during training, or simply as inspiration. Some of the workouts can also be followed step by step, which allows for simultaneously connecting to a kMeter and registering data during the workout.

### 1/5 — Terrible app and poor instructions

*2024-08-29*

Can’t find any simple, clear guidance on the web site, app or manuals that helps with k-meter setup and install on the kbox active platform.  Really bad first impression. Chat Bots on the web site keep indicating that they are redirecting my requests but no human response or useful responses.

### 2/5 — The audacity to charge subscriptions

*2024-01-18*

It’s kind of unbelievable that after most of us drop at least $2K on a kbox or some combination of equipment from you guys and you have the nerve to actually charge a subscription on your workout app? And worst of all you haven’t even updated this thing in years. You should make this app and all content free immediately. You will sell way more of these K boxes.

### 2/5 — Poor UX and buggy

*2023-05-17*

I spent $4k on a Kbox and accessories and the app is sorely lacking for the investment. The UI/UX is not intuitive. It frequently doesn’t log exercises and crashes too often. Disappointed with my purchase.

**Developer response:** Hello, thank you for reaching out. We are sorry to hear you are experiencing issues with your app. We can have our team take a look if you wanted to fill out our app support form so we can resolve this issue for you. Here is our app support link - https://exxentric.com/help/technical-support/app-support/

### 5/5 — 5 Star Tech Support Response

*2020-12-01*

After a woeful App update that contained numerous and significant errors the Exxentric team responded promptly and were actively engaged with me to resolve all of them. It took some time to eliminate all the bugs, but they were persistent and it’s finally error free from my perspective. This bodes well for the continued success of this company. As an aside the inertia devices are great. I’ve noticed strength and hypertrophy gains after swapping from traditional weight training. This occurred even after several decades of traditional resistance training and my age of 58!

**Developer response:** Hello Seillier, thank you for sharing this with us. We are happy that our team was able to resolve this issue for you! Please feel free to contact us with any further questions or comments.

### 1/5 — Latest update messed it up

*2020-11-21*

Worked great until recent update. Now the inertia settings don’t line up with the plates you select

**Developer response:** Hey cgd1222, sorry you experienced this issue with your device. Hopefully this is not still occurring. If so, please reach out to our App Support so our team can help you get this resolved - https://exxentric.com/help/technical-support/app-support/

### 5/5 — Love this!!!

*2015-07-14*

I have the KBox3 and this app definitely feels like it completes the total usage of the equipment! Hearing power output go change motivates myself and my athletes to push harder and harder. Great job Exxentric!!!

**Developer response:** Thank you for sharing!
